Abstract

The system size dependence for multiparticle processes has been recognized in both cosmic ray (“Stratosphere” collaboration) and at accelerator (“EMU” collaboration) experiments. The strong enhancement in multiplicity fluctuations for the most central light-light – (C, O, Ne) + (C/N/O) – collisions has been revealed at JINR-AGS-SPS energies. The sharp difference of light nuclear interactions are interpreted as the sign of intrinsic alpha-clustering in light nuclei.

Introduction

Understanding the initial stages of high energy nuclear interactions is one of the key problems for heavy ion physics. To understand the problems of particle production in cosmic ray interactions the ever-increasing forward physics programs are considered at the LHC and RHIC colliders [3]. A better understanding of the initial state characteristics can be obtained from small system interactions. These problems were considered at QM 2014 [6], and at WWND 2016 [7] and more detailed at QM 2015 [8]. In this work the system size dependence for multiparticle processes is considered at cosmic ray and accelerator experiments. 2. The difference of multiparticle processes generated by cosmic ray protons and light nuclei. There are some serious problems [12] to perform this analysis
